CodedOutputStream

java.lang.Object
- com.google.protobuf.CodedOutputStream

```
public final class CodedOutputStream
extends Object
```
Encodes and writes protocol message fields.
This class contains two kinds of methods: methods that write specific protocol message constructs and field types (e.g. writeTag(int, int) and writeInt32(int, int)) and methods that write low-level values (e.g. writeRawVarint32(int) and writeRawBytes(com.google.protobuf.ByteString)). If you are writing encoded protocol messages, you should use the former methods, but if you are writing some other format of your own design, use the latter.

This class is totally unsynchronized.

  - writeRawLittleEndian64
```
public void writeRawLittleEndian64(long value)
                            throws IOException
```
    Write a little-endian 64-bit integer.
    
    Throws:
    
    IOException
  - encodeZigZag32
```
public static int encodeZigZag32(int n)
```
    Encode a ZigZag-encoded 32-bit value. ZigZag encodes signed integers into values that can be efficiently encoded with varint. (Otherwise, negative values must be sign-extended to 64 bits to be varint encoded, thus always taking 10 bytes on the wire.)
    
    Parameters:
    
    n - A signed 32-bit integer.
    
    Returns:
    
    An unsigned 32-bit integer, stored in a signed int because Java has no explicit unsigned support.
